Just curious, but is there a way to determine what games require a specific bios file? Some of them are pretty obvious, but not all.
What purpose do the chd files have, and how do you know if one is needed?
Questions about Bios/chd's etc.

if you do an audit on the rom set, it will show you what rom files are missing. Normally you can see if a bios is needed from the missing list.
chd files are a compressed hard drive image file format....which more modern games in mame use.
the arcade games for these have actual hard drives etc. with the data on them.
I can't wait til mame has opengl use module to support the 3dfx arcade games

Click on the file name to see what games require it.

[quote="mahlemiutNot quite. CHD = Compressed Hunk of Data. It represents large storage media, typically hard disks or CD-ROMs[/quote]
yeah, after the fact I realized many have it on CDs.
how far is mame from supporting laser disc games? sure, we have daphne, but it would be cool to have the laser disc image and mame play the game from those.

yeah, I can see licensing issues there perhaps.
it sounds more like where they want mame to be totally it's own thing...
in other words, if they could compile the codec within mame for the support, the developers would do it...but since it would require installing of someone else's software and reference the lib etc. they want no part of it.
oh well...not much you can do there.

good point....I wonder how large a "proper" laser disc dump would be.
it seems a truly accurate one would require a TV-card or equivalent to play the raw signal data...or was a codec actually used for those games?!?
I just remember those laser discs were huge...but perhaps no more data than a CD-ROM has nowadays?!?

Nah, more than a CD-ROM. They sell it in DVD at digitalleisure. Merely my Dragon's Lair Daphne converted video+sound takes 957MB hard disk space.
I don't get the difference between analog and digital here. Analog=movie, digital=computer...right? In order to play it with a computer it HAS to be converted to digital format, unless you have a movie disk and emulate movie playing hardware too. Did I get it right?

another way to perhaps say it is digital is data that just consists of zeroes and ones...
each site location on digital media is either 0/1 in value. or off/on...magnetized, not magnetized, etched, not etched, etc.
On analog media, you don't have 0/1s...but a stored degree of magnetism(in the case of VHS tapes, cassettes etc.
